4 Claims. (Cl. 214%510 This invention relates to. earth moving apparatus or the like and has particular reference to new and improved features adapted for use with: a tractor carried apparatus such as the back hoe set forth in my application filed November 14, 1949, Serial Number 127,170 and now abandoned.

This application isa division of my application Serial Number 185,841, filed September 20,. 195() nowePatent Number 2,678,741.

An object of the invention is to provide new and improved buckets for a device of the type set forth which is entirely hydraulically operated and which is carried by a tractor and obtains its power from the tractor engine.

Another object is to provide a bucket for devices of the type set forth which bucket is provided with a cleaning arrangement which makes the bucket. particularly adaptable for use in handling gooey or other materials with which assistance in emptying or frequent cleaning of the bucket is desirable.

Another object is to provide a boom attached bucket arrangement whereby said device may be employed as a loader.

An important object of the invention is to provide a new and improved bucket and bucket operating mechanism.

Another object is to provide such a bucket and bucket operating mechanism with which it is possible to open the bucket instead of opening the bucket door and thereby gaining reach and also with which it is possible to clamp material between the bucket door and the bucket and also to dig with the front end of the bucket.

Other objects and advantages of the invention will be apparent from the following description taken in connection with the accompanying drawings. It will be understood that changes may be made in the details of construction and arrangement of parts without departing from the scope of the invention, as the preferred forms have been given by way of illustration only.

Referring to the drawings:

Fig. l is a side view of one form of bucket embodying the invention;

Fig. 2 is a side view of another form of the bucket;

Fig. 3 is a sectional view taken on line 3-3 of Fig. 2 looking in the direction of the arrows; and

Fig. 4 is a fragmentary side view showing the bucket cleaner operating arrangement.

Referring more particularly to the drawings wherein similar reference characters designate corresponding parts throughout, there is shown in Figs. 1 through 4 of the drawings two forms of bucket especially intended for use as either a trencher or loader bucket, in either direction for use in handling materials, such as gooey materials, which require frequent cleaning of the bucket and/or means for removing the material from the bucket during dumping, although they could be used for handling other materials if desired.

This construction also eliminates one of the drawbacks of existing arrangements which require changing over 2,719,641 Patented. Oct. 4, 1955 from trenching to loading which required the actual changing of the bucket, whereas with the bucket of the present construction the device can be converted from a trencher to a loader without any change except the moving of the blade or paddle to one or the other end of the bucket. Thus, the paddle shown in the center of the bucket can be used as an end or closure of the bucket and can be used to close either end and, if desired, the material can then be pushed through the bucket or the paddle or door can be dropped down to allow the material to spill.

For example, in grave digging where it is desired to make poth ends of the hole vertical, this bucket can be used to dig vertical at both ends merely by moving the paddle which may be easily and quickly accomplished without loss of time.

In the arrangement shown in Fig.- 1, the dipper stick 13 is: pivotally connected to boom 11 at 14 and adapted to be actuated by ram 28. In this construction bucket 86 is open at its opposite ends and held in fixed relation to dipper stick '13 by link 87 which is connected at its oppositeends to said dipper stick 13' and said bucket 86.

A pair of substantially U shaped arms 88 and 89 are pivotally connected to dipper stick I3 and also to member 90 which is of such size as to be pushed through the open end of bucket 86' and which can be used to fill, empty or clean bucket 86.

Arms 88 and- 89, and pusher 90 are adapted to be actuated by ram 91 which is pivotally connected to said arms at its free end. and which is connected to a double acting piston in cylinder 92 which is pivotally connected at 9 3 to dipper stick 13' adjacent its upper end. Hydraulic lines 94 and- 95 are connected tov opposite ends of cylinder 92 for supplyingpower thereto. 7

The arrangements of Figs. 2, 3 and 4 are generally similar to that of Fig. 1 except for the bucket filling and emptying arrangement.

In the construction of Figs. 2 and 3, the paddle or pusher member 96 is pivoted to dipper stick 13 at 97 and a linkage arrangement is provided between ram 91 and said member 96 which linkage arrangement consists of link 98 which is pivotally connected to ram 91 at 99 and to member 96 at 100, and link 101 which is also pivotally connected to ram 91 at 99 and to dipper stick 13 at 102. In Fig. 2 there is shown in dotted lines the relative positions of member 96 and links 98 and 101 when the member 96 is moved to various positions.

In the construction shown in Fig. 4, link 101 is pivotally connected to pivot 97 instead of pivot 102.

It will be seen from the above that in the forms of the invention shown in Figs. 1 through 4 that the bucket 86 and the member 90 or the member 96 can be pivoted as a unit by pivoting the dipper stick 13'by which said bucket and said member is carried, by actuating the piston and ram 91 in cylinder 92 and member 90 or 96 may be moved to desired position relative to bucket 86 to close either end of the bucket or to push material out of the bucket as desired, and thus providing a construction which it is capable of providing all of the objects and advantages of the invention.
